shopify free shipping threshold killing margin
Free-shipping thresholds that fight discounts train customers to game cart math. Align rules, then re-test the promo path operators actually use.
The actual problem
Free-shipping thresholds set below contribution margin turn every promo into a loss leader.
Do this
- Compute contribution margin after shipping for top 20 SKUs.
- Set free-shipping threshold above the cart that still clears margin + ads CPA.
- Kill stacking of free-shipping codes with % discounts.
- Re-check paid landing pages still mention the correct threshold.
